A particularly challenging area of study within proteomics is post-translational modification of proteins.
having introduced ETD (electron transfer dissociation) in 2005 as the first vendor, Bruker Daltonics is now taking the next major step forward: data-dependent, intelligent combinations of CID and ETD on an HCT Ultra(TM) high-capacity ion trap for maximum information on sequence coverage and post-translational modifications in complex samples will be described.
